Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ151030831-00 §1.1307 (b) (1) &§2.1093 – RF EXPOSURE Applicable Standard According to FCC §2.1093 and §1.1307(b) (1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. According to KDB 447498 D01 General RF Exposure Guidance The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where 1. f(GHz) is the RF channel transmit frequency in GHz. 2. Power and distance are rounded to the nearest mW and mm before calculation. 3. The result is rounded to one decimal place for comparison. 4. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test Exclusion. Evaluation data: The maximum tune-up conducted peak output power is 20 dBm(100 mW) @1928.448 MHz And Duty Cycle = Ton/Tp*100% = 4.10% Which, Ton = 412 μs, Tp= 10.05 ms, please refer to the report RSZ151110830-00 with model number RF1G9V1 (FCC ID: B4HRF1900V1) page 44 and 45 for plot detail So,the maximum conducted source-based, time-averaged output power is: 100*4.10%mW=4.10 mW@1928.448 MHz (4.10/5)* √1.928448=1.1<3.0 Result: No SAR test is required FCC Part 15D Page 8 of 22

(Shenzhen) Report No.: RSZ151030831-00 FCC§15.317 & §15.203 - ANTENNA REQUIREMENT Applicable Standard According to FCC § 15.203, an intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this Section. The manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited. Antenna Connector Construction The EUT has one integral antennas arrangement, which was permanently attached and the gain is 0 dBi, fulfill the requirement of this section. Please refer to the EUT photos. Result: Compliant. FCC Part 15D Page 9 of 22

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ151030831-00 FCC§15.319 (g) - RADIATED EMISSIONS Applicable Standard According to FCC§15.319(g), notwithstanding other technical requirements specified in this subpart, attenuation of emissions below the general emission limits in §15.209 is not required. Measurement Uncertainty All measurements involve certain levels of uncertainties, especially in field of EMC. The factors contributing to uncertainties are spectrum analyzer, cable loss, antenna factor calibration, antenna directivity, antenna factor variation with height, antenna phase center variation, antenna factor frequency interpolation, measurement distance variation, site imperfections, mismatch (average), and system repeatability. Based on CISPR 16-4-2:2011, the expended combined standard uncertainty of radiation emissions at Bay Area Compliance Laboratories Corp. (Shenzhen) is 5.91 dB for 30MHz-1GHz.and 4.92 dB for above 1GHz, and it will not be taken into consideration for the test data recorded in the report EUT Setup Below 1GHz: FCC Part 15D Page 10 of 22

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ151030831-00 Above 1GHz The radiated emission tests were performed in the 3 meters test site, using the setup accordance with the ANSI C63.17 - 2013. The specification used was the FCC 15§ 15.319(g). The external I/O cables were draped along the test table and formed a bundle 30 to 40 cm long in the middle. EMI Test Receiver & Spectrum Analyzer Setup The system was investigated from 30 MHz to 20 GHz.

(Shenzhen) attests that all calibrations have been performed in accordance to requirements, traceable to National Primary Standards and International System of Units (SI). Corrected Amplitude & Margin Calculation The Corrected Amplitude is calculated by adding the Antenna Factor and Cable Loss, and subtracting the Amplifier Gain from the Meter Reading. The basic equation is as follows: Corrected Amplitude = Meter Reading + Antenna Factor + Cable Loss- Amplifier Gain The “Margin” column of the following data tables indicates the degree of compliance with the applicable limit. For example, a margin of 7dB means the emission is 7dB below the maximum limit. The equation for margin calculation is as follows: Margin = Limit - Corrected Amplitude Test Results Summary According to the recorded data in following table, the worst margin reading as below: 15.63 dB at 260.3 MHz in the Horizontal polarization for Low Channel (Model No.:ComStar Xtreme(HDST1915)) Refer to CISPR16-4-2:2011 and CISPR 16-4-1:2009, the measured level is in compliance with the limit if Lm + U(Lm) ≤ Llim + Ucispr In BACL, U(Lm) is less than Ucispr, if Lm is less than Llim, it implies that the EUT complies with the limit.
